Farhan Akhtar and Sidhwani's production company, Excel Entertainment, owns the rights of the Amitabh Bachchan-starrer 1978 film "Don".

"Don" (2006) and "Don 2" (2011) also starred Priyanka Chopra opposite Shah Rukh Khan, who stars in the title role. Speculations are rife especially over Priyanka's character, Roma. According to reports, Deepika Padukone's name had emerged to replace the "Quantico" actor. When asked if the makers can play around with the central characters, especially that of Priyanka's, Sidhwani said it is too early to comment.
